bishop knight checkmate indicator

I did it once in a blitz game. I was really happy with myself.

A different time I was playing an expert in a friendly blitz game OTB. He had 1 minute on the clock... no delay or increment... I laughed out loud as I took his last pawn, because I thought he'd never do it... but he did it. I was super impressed. (turns out he was some endgame freak, reading Nunn's Secrets of Pawnless Endings every day).

Anyway to answer your question, this is how it went for me.

First I learned it from a book. I practiced it a few times just me vs me. Then I practiced a few times vs a computer.

Then a year later I try to remember it and I screw it all up, so learn it again (this time with help from Widipedia which shows different ways to do it), I practice vs myself, and I practice vs computer.

Then a year later, etc.

I've done this 3 or 4 times. Each time it gets a little easier and makes a little more sense.

Of course the basics is super easy... your knight stays on the same color as the bishop. When you move the knight it's usually a pair of moves (to get it back to the same color) and you just slowly push the king in the corner... so in a way it's a little shameful that it took me this much work, but that's how it is.

I learned it a couple of years ago. It's really easy for me now. I've practiced it enough so that I can consistently do it in 30 seconds or less against the computer.
